For a (comparatively long distance) travel map, I rather like AAA's regional maps (i.e. Northeast states and provinces, or the other quadrants). If you have the space,
The Imus Geographics Essential Geography of the United States of America map is superb and the laminated version can be drawn on with dry-erase markers (and erased/cleaned afterwards) if needed. I sometimes wish I had a big blank wall in my motorhome waiting for it.
